搜索发现，可以这样解决：
<script language="javascript" type="text/javascript">
function closeWindow() {
  window.open('','_parent','');
  window.close();
  }
  </script>  
  <a href="javascript:closeWindow();">Close Window</a>

  好多朋友用到是自动关闭页面代码
  <script language="javascript">
function closeWindow(){  
window.open('','_parent','');  
window.close();
}
setTimeout("closeWindow()",3000);
</script>
